CONDUCTIVITY/EC/TDS/SALT CALIBRATION PROCEDURE and MEASURING
NOTE: Calibration is necessary before operation, the calibration procedures refer to as below “ a) to b)”:
2-1 Conductivity
a) Required Equipment for calibration:
1) Cond./EC/TDS/SALT ELECTRODE
2) Prepare the standard 1413 uS conductivity solution.
Toggle 1413 uS calibration mode to 12.8 mS calibration mode (under Conductivity calibration mode).
NOTE: Make sure to use fresh solution each time due to the contaminants in the solution will affect
the calibration and the accuracy.
b) Calibration Procedure:
1) Prepare the Conductivity electrode, install the “electrode plug” into the left
“BNC port” of the meter.
2) Power on the meter by pressing PWR button.
3) First, to enter the cell constant (K) value of the Cond. electrode is required
(e.g. Refer to the label on the top handle of the probe.)
Long press SET+UNIT to enter the cell constant value. Units digit will flash.
HOLD:
↑
to increase ADJ:
↓
to decrease SET:
←
to left digit CAL:
→
to right digit
And long press SET to save setting, screen will show “SA”.
To escape calibration mode without saving setting, long press SET+UNIT button, the bottom of screen
will show “ESC” few seconds and return to normal measurement mode.
4) Conductivity electrode (K = 1):
Long press SET + CAL buttons to enter Cond. calibration mode. Immerse the cond. probe to standard 1413
uS buffer solution. Display will show the standard conductivity 1413 uS values. Long press SET button to
finish calibration, screen will show “SA”.To escape calibration mode without saving setting, long press
SET+CAL button, the bottom of screen will show “ESC” few seconds and return to normal measurement
mode.
